UNITED STATES PATENT OFFICE.

WATSON EATDOREE, OF CANTON, OIIIO.

SHEET-METAL ROOFING.

SPECIFICATION forming part of Letters Patent No. 432,176, dated July 15, 1890.

Application filed June 17, 1889. Serial No. 314,622, (No model.)

To all whom it may concern,.-

Be it known that I, WATSON BATDOREF, a citizen of the United States, residing at Oanton, in the county of Stark and State of Ohio, have invented certain new and useful Improvements in Sheet-Metal Roofing; and I do hereby declare that the following is a full,

clear, and exact description of the same, reference being had to the annexed drawings, making a part of this specification, and to the letters of reference marked thereon, in which- Figure l is a view of the sheets and anchor, showing the same apart. Fig.' 2 is a view showing the anchor placed in position and one of its parts partially folded. Fig. 3 is a transverse section of the roofing-sheets, showing the anchor placed in position and partially folded. Fig. 4 is a transverse section of the sheets, showing the anchor-sections properly folded. Fig. 5 is a transverse section showing the seam partly formed. Fig. 6 is a View in section, showing the seam properly formed. Fig. 7 is a view showing` the seam formed.

The present invention has relation to sheetmetal roofing; and it consists in the different parts and combinations of parts hereinafter described, and particularly pointed out in the claim.

Similar letters of reference indicate corresponding parts in all the figures of the drawings.

In the accompanying drawings, A represent portions of the roofing-sheets, which may be formed of any desired length; or, if desired, these sheets may be formed in sections and the sections properly united at their ends by suitable cross-seams or locks. One side of the sheet- A is provided with the tongued-up portion a., and at the point where anchors are to be placed said tongued-up portion a is provided with the slit I), which is for the purpose of passing the tongue c through, as illusf trated in Fig. 2.

The anchor B is formed double, thereby forming the sections or leaves (l and d. The

section d is provided with the tongue c, which is formed long enough to pass a short distance above the top or upper edge of the tongued-up portion ct and be bent or folded over said tongued-up portion ct. The top of the section or leaf d is drawn a short distance away from the section d for the purpose of properly folding the tonge c, as illustrated in Fig. 3, at which time said section CZ is pressed or forced back against the section d', when the adjacent sheet provided with the tonguedup portion d is placed in the position illustrated in Fig. 2, at which time the section or leaf d is bent or folded over the tongued-up portion a', as illustrated in Figs. 4, 5, and t5.

The tongued-up portion a, which extends above the tongued-up portion a', is bent or folded over the tongued-up portion ct', as illustrated, Fig. G, and at the same time the leaf d', together with its tongue, is carried with the tongued-up portion a over the tongued-up portion ct.

It will be understood that the anchor B is to be securely nailed or otherwise fastened to the sheeting of the rooi` proper.

As shown, the tongue c is out or formed at one side of the anchor B and it will be understood that the same object can be accomplished by forming said tongue at any other place; but- I prefer to form it as illustrated in the drawings. The shoulder e is for the purpose of abutting against the tongued-up portion u., and thereby securely looking the sheet to which the tonguec is attached and prevent any displacement of said sheet. The part of the tongued-up portion a above the slit b should be sprung a little to one side for the purpose of more easily entering the tongue c.

IIavin g fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

The combination of the sheets A, provided with the tongued-up portions a and d', the anchors B, having sections or leaves d and d', said sections being united at their bottom or lower ends and formed of a continuous strip of metal, the tongue c, adapted to pass through the slot b and folded over the tongued-up portion a., the leaf CZ, adapted to be folded over the tongued-up portion a', the shoulder e, adapt-ed to lock the anchors B in position, and the tongued-up portion a folded over the tongued-up portion a', substantially as and for the purpose set forth.

In testimony that I claim the above I have hereunto subscribed my name in the presence E. A. C. SMITH, F. W. BOND.
